Solution: Convert Sorted Array to Binary Search Tree

Explore how to build a height-balanced binary search tree from a sorted integer array by selecting middle elements recursively as roots. Understand the recursive process that ensures balanced subtrees and optimal tree height. Gain insight into time and space complexity of this approach applied in C++ coding patterns.

We'll cover the following...

Statement

Given an array of integers, nums, sorted in ascending order, your task is to construct a height-balanced binary search tree (BST) from this array.

In a height-balanced BST, the difference of heights of the left subtree and right subtree of any node is not more than 1.

Note: There can be multiple valid BSTs for a given input.

Constraints:
